To all whom 'it may concern:

Be it known 'that I, INoniiie'r J. GLERUM, a citizen of the UnitedStates, residing at Devils Lake, in the county of Ramsey and State ofNorth Dakota, have invented certain new and useful Improvements in Life-Line Projectiles; and I do declare the f ollowing to be a full, clear,and exact description of the invention, such as will. enable othersskilled in the art to which it appertains to malte and use the semenThis invention relates to improvements in projectiles for carrying lifelines.

One object of the invention is to provide a projectile of this characterconstructed in such manner and of suoli material that it will not injureanyone' when falling to the ground after having been projected forcnrrying the life line to the desired point.

Another object is to provide a life line projectile of this characterhaving an imroved construction and arran ement wherey the line willfreely uncoi and pay out fron the projectile without becoming tanle gAnother object is to provide means where by the compressed air or otherpropelling Huid will be prevented from disturbinu the arrangement of theline in the projecti e or interferin with the proper unwinding of thecoils W en the projectile is discharged.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more full described and particularly pointed out in t e appendedclaims.

In the accompanying drawings: Figure 1 is a side view o my improvedline'cerrying projectile; Fig. 2 is a. similar view showing the partsseparated; Fig. 3 is a centrallongiformed of tudual sectional view ofthe projectile; Fig. 4 is a. vertical cross sectional view on the line4-4 of Fig. 1; Fig. 5 is n. longitudinel sectional view of a. modifiedform o the projectile. Fi 6 is a detail sectional view of a portion othe pro'ectile showing the menner in which the dis rs are arrangedbetween the balls of cord in the projectile and the manner in which thecord passes around end between the disks from one ball to another.

My improved projectile is preferably paper but may be constructed ofany. siiitab e material which will not be likely to cause injury ordamage when felling to the ground after having been projected.

The projectile as shown in the first figures of the drawing comprises atubular cylindrical body portion 1 in the outer end of which is arrangeda bullet shaped head 2 formed of suit-able material for imparting theproper weight to the outer end of the projectie und to partly overcomelthe resistance of the outpaying of the line. The head 2 is detacliablysecured in the outer end of the body 1 in any suitable manner and ishere shown as being preferably secured by means of a series of studs 3formed on the inner surface of the outer end of the body 1, preferablyformed by indenting the side of the tube as shown. In the outer side ofthe inner end of the head 2 is formed a series of right angularly shapedgrooves 4 in which the studs 3 are adapted to be engaged when the headis inserted into the outer end of the body and turned in the properdirection thereby fastening the head in the end of the tube und forminga fluid tight joint.

The line is arranged in the body 1 of the projectile in the form of aseries of balls 5 wound in the same manner as an ordinary ball of twineis wound and between each two balls when placed in the body 1 isarranged a series of loose disks 6 formed of peper as shown in Figs. 3,5 and 6 separating the balls and preventing the nressure of the air orother projectin iiuid rom dislocn-ting the coils in t-he ba s of theline and thus causinlthe latter to pay out double or to become ngled.The inner end of the line of one ball is passed diametrcally around andbetween the disks'between it and the next ball and is connected with theouter end of the line of the next ball toward the inner end of theprojectile, und the outer end of the line of the first ball in the frontend of the irojectile being connected to the head or en of theprojectile. The inner end of the rear or-innerinost ball in theprojectile is secured in any suitable manner in the end of the gunbarrel from which the projectile is thrown. The pressure of thepropelling fluid, in the absence of the separatin disks would tend topress the balls tege er an cause their adjoining coils to become mattedor entangled but this is preientecl by the disks, an as the end of theline of each ball is reached in paying out the line, the pull on theline will tip the -in rane ortction or from sli dicke of the seriesconsecutively but in opposite directions so that the continued eyout ofthe line will not be inter ered w1 In order to prevent the contente ofthe projectile from becoming damp or from bein disturbed in any mannerthe rear end of e projectile is preferably sealed by c suitable oep 7which is preferably constructed o f wax paper or other similar materiel,seid oep being adapted to bc 'removed when the pro'ectile ie placed inthe gun, In the rear en of the proectile is crranhed c sto coller 8which is a opted to hold e ball mly pressed together and to revent theseme from bein shaken while out of the rear en of the projectile while elatter is in motion. The co ler 8 is glued or other wise suitablysecured to the inner side of the pro'ectile In 5 of'the drawing'is shownc. Slightly modiied construction of projectile 9 `1n which the outer endof the tube is crun ed or otherwise drawn together and seele by luing orotherwise cementing the 'come to er to form e duid tight closure.

The lat er form of the projectile is adapted more especially for use inconnection with lince thrown over or into a. burning building v vhereinthere is danger of the projectile str1 the occupnntsof the build' orwhen wn over the building from flgin i uponn one passin by the o csiteside o the bui d' B orming' ero'ectile without .euhgead just describedIihcJseme will be light in weight and will not be c t to injure any oneif struck thereby. In th form of the pro ectile the bells of cord ortwine forming t e line rovide the necessary wel ht for ecus accurateprojectile ie eee fet-merece there cra o su cien rnu e roectilto esaover e buildein and own on t e opposite side thereo Frein the foregoingdescription taken in connection with the accompanying drewinge, theconstruction and operation of the invention will be readily understoodwithout g a more entended explanation erious Ieh es in the form,proportion endthe minor etails of construction may Ucplel et this yatcntmy he attained for me centi smh, by cddrcssing the Uommluioner closedandV etgrcjeotile to be' en e beresorted to without depertin from the'rinciple or sacrificing any ol he advences of the invention as claimed.

loving thus described my invention what I claim is:
